To all whom t may concern:

Beit known that I, HERBERT A. VINING, a citizen of the United States,residing at Arlington, county of ,Middleseig Commonwealth ofMassachusetts, `have invented certain new and'useful Improvement-sinMops, of which the following is a specification.

This invention relates to mops, and particularlyto the mop headstructure and the means for clamping the mop material to the mop head. i

The object of my invention is to provide a simple, inexpensive andattractively de# signed mop head and clamp for reliably clamping the mopmaterial in place, so con* structed andarranged as to dispose the entireworking face of the mop in a pla-ne parallel totheoor 0r othersurfacebeing cleaned. This object and Certain other advantages whichwill appear more particularly hereinafter are secured in the device ofthe present invention, the construction and operation of which is fullyexplained in the specification which follows, illustrated f in theaccompanying drawings, and particularly pointed out in the appendedclaims. rlhroughout the specification and drawings, like referencecharacters are correspondingly employed, and in the drawings Figure 1 isa top plan view of a mop head in accordance with my invention.

Fig. 2 is a bottom plan view thereof. Fig. 3 is a longitudinal sectionthrough the i mop head on theline of Fig. 2,-show ing in dotted linesthe position of the clamp retaining fingers before clenching,a nd

y, Fig. l is a detail view'of the resilient mop material clamping memberremoved, the re` silient character of said member being indicated by thesolid and dotted line showing.

I have indicated at 1 a mop head and at 2 any suitable mop materialadapted to be clamped to said head.

According to this invention, the mop ma terial 2 is adapted to beclamped to the head 1 in such manner as to present a substantially flatworking vface to the floor. Each individual strand of the mop materialis therefore clamped to the head at substantially its center so that thestrands are doubled upon themselves and have their free ends exposed asflat mopping surfaces.

As here shown the head 1 is of triangular shape and is so drawnorotherwise shaped as to slope downwardly in three directionsSpecification of Letters Patent. Pghtntdl Dig@ Application inea October3i, i917. serial No. 199,543.

from its center producing yahead of general pyramidal form.` Thisconstruction provides an internal cavity in which a portion of the mopmaterial may lie. The upwardly inclined seat l1` formed by the pyramidalshape of the head is cut out to receive agenerally sphericalsocketmember or cup 3 which may be rigidly secured to the head 1 by `upsettingits inner end Vto form a flange i by means of which the cup may besoldered'to the internal face of the head. The

inclined seat l1 of the generally pyramidal headprovides for theconnection of the han- `dle with the head at an angle,` whereby the iworking face of the mop is disposed in a plane parallel to the floor orother surface to be inopped, and the entire working face of the mop thusexposed, whilethe handle itself extends at an oblique angle to thefloor.

The handle `may be secured to the head by means of a bolt 5 set throughthe socket member or cup 3 at substantially right angles to the plane ofthe seat 11, and carries on its inner end a securing iiange 6 which maybe curvedto conform to the curvature of the internal surface of the cup3 and may be secured to the bolt within said cup `in y. a, iaiaj anysuitable manner as by hammering over i the head of the bolt, (see Figs.`2 and 3), The opening in the cup 3 through which the bolt 5 passes maybe concealed by any suit-` able shield 61 whichis preferably run downupon the bolt until it abuts the socket ment ber 3 and there made fastto the bolt in any desired manner.

The mop material is adapted to be clamped tothe head lwithin theperimeter thereof and at the centers of the individual strands. For thispurpose `the perimeter of the head is `bent downward to provide asubstantially `vertical edge 7 against the inner face of` which thematerialmay be clamped `by a clamping member 8 whichmay be held to thehead internally thereof by a series of spaced depending lingers 9 formed`along the edge 7 (see dotted line showing Fig. 3), and adapted to beclenched down over the clamp' 8, (see solid line showing Fig. 3). Theclamp `8 may be a simple wire bent to a substantially triangular formand adapted tof snugly lfit the internal face of the `head against theclamping edge 7 thereof. By making the clamp of resilient material (secFig. 4l) the operation of forcing the clamp toits seat 7 puts the clampunder tension and this tension not only assists te maintain the clamp inplace due to the tendency of the wire to expand, but causes the wire tofirmly clamp the-mop material between it and the edge 7 of the head.This clamping action is best illustrated in Fig. 2 wherein the mopmaterial is shown as clamped at the centers of its individual strandsbetween the clamping wire and the edge 7 of the head, and the retaininglingers are shown as bent down over the clamping wire.

It will thus be observed that the head l may be formed as a simplestamping into which the spherical cup 3 and bolt 5 may be readily set atthe proper angle, and that the clamping member 8 readily seats withinthe vertically disposed edge 7 of the head and by reason of itsresilient nature not only. tends to lodge itself therein, but acts tofirmly clamp the mop material to the head.

Various modifications in the form and construction of my device mayobviously be resorted to if within the limits of the apf pended claims.

What I therefore claim and desire to secure by Letters Patent is:

l. A triangular sheet metal mop head having a raised semisphericalportion extending above 'the upper surface thereof, and a downwardlyextending peripheral flange,` said semi-spherical portion constituting aseat for a handle connection, and a triangular shaped length ofresilient wire expansibly lodged within said head and adapted to clampstrands of mop material against said flange.

2. A sheet metal mop head having a downwardly extending peripheralflange against the internal face of which strands of mop material areadapted to be clamped, and a resilient clamping member shaped to conformto the shape of said mop head at said flange, and adapted to becompressed and lodged within said head and tending when released t0expand and clamp the mop material between itself and said flange.

3. A triangular sheet metal mop heald having a raised seat portionextending above the upper surface thereof and a downwardly f extendingperipheral flange, the working face of the mop head being substantiallyflat, and said seat portion adapted to receive a handle connection, atriangular shaped. length of resilient wire expansibly lodged withinsaid head and adapted to clamp the individual strands of a body of mopmaterial at their centers between itself and the peripheral flange ofthe mop head, and fingers on said flange adapted to be clenched oversaid wire to retain it in place.

4. A sheet metal mop head having a downwardly extending peripheralflange against the internal face of which mop material is adapted to beclamped, and a length of resilient wire shaped to conform 'to the mophead at said flange and adapted to be compressed and lodged within saidhead and tending when released to expand and clamp the mop materialbetween itself and said flange.

5.1i. mop head having a seat portion for a handle connection raisedabove the upper surface thereof and having a downwardly extendingperipheral flange, against the internal face of which strands of mopmaterial are adapted to be clamped, and a resilient clamping membershaped to conform to the shape of said mop head at said flange, andadapted to be compressed and lodged within said head and tending whenreleased to expand and clamp the mop inaferial between itself and saidflange.

In testimony whereof I aflix my signature in presence of ltwo witnesses.
